Everything You Need to Start Controlling the GPIO of Your Raspberry Pi With Node-RED
The Raspberry Pi Foundation has released a new guide for Node-RED, one of the easiest ways to manage your Raspberry Pi’s GPIO pins and connect your Pi to the outside world.
To use this guide, you will need a Raspberry Pi, breadboard, buttons, some LEDs, and some wires. From there, the guide will walk you through the Node-RED program to control these lights and a lot of other GPIO activities. If you’ve hesitated to mess around with GPIOs, now is the time to learn how, and this tutorial is easy to follow.
